A large fraction of the current Internet traffic is caused by video streaming. Due to the growing expectations of video consumers, monitoring video applications is getting more and more important for network and service providers. In a previous work, we proposed a video quality monitoring solution which utilizes the full reference SSIM metric to im...

In the past decade, video streaming has taken over a large part of the current Internet traffic and more and more TV broadcasters and network providers extend their portfolio of video streaming services. With the growing expectations of video consumers with respect to the service quality, monitoring is an important aspect for network providers to d...

Software Defined Networking (SDN) is a new paradigm for communication networks which separates the control plane from the data plane of forwarding elements. This way, SDN constitutes a flexible architecture that allows quick and easy configuration of network devices. This ability is particularly useful when networks have to be adapted to changing t...

Applications and resource allocation within the network become more and more flexible in supporting divergent user demands. This is reflected by state-of-the-art video codecs like H.264/SVC which allow a dynamic adaptation of the video quality and therewith the required network resources. Within the network, techniques like network virtualization a...

More and more services are provided by large data centers with a potentially very large number of physical or virtual hosts. As the number of hosted services and service consumers increases, also the number of hosts inside a data center raises to cope with the increasing end-user demand. Current data center networks are usually based on Ethernet an...

The Locator/Identifier Separation Protocol (LISP) is a new naming and addressing architecture which is currently standardized in the IETF and which is deemed to improve the scalability and flexibility of the current routing architecture. LISP mobile node (LISP-MN) is an extension to the basic LISP architecture and enables mobile nodes to roam into...

Concurrent multipath transport layer mechanisms have gained recently increasing interest in research and standardization because of the potential for bandwidth aggregation, load balancing and increased reliability. Multihomed end devices may benefit from IP-based multipath protocols like Multipath TCP or Concurrent Multipath Transmission via SCTP....

We recently witness new services that can afford some delay until data transmission starts, but then benefit from a very large available bandwidth. A popular example is the migration of virtual machines between different sites of a geographically dispersed service provider. In this paper, we propose a subscription model for time-scheduled data tran...

The Locator/Identifier Separation Protocol (LISP) is a new routing architecture for the Internet that separates local and global routing. It offers more flexibility to edge networks and has the potential to reduce the growths of the BGP routing tables. Recently, a concept for mobility in LISP (LISP Mobile Node, LISP-MN) was presented. We analyze LI...

The current inter-domain routing architecture faces scalability issues regarding the growth of the active entries in BGP routing tables. Several new naming, addressing, and routing technologies are currently under discussion in the IETF and

The Locator/ID Separation Protocol (LISP) is currently being developed and standardized in the IETF aiming to solve the Internet's routing scaling problem. It separates global routing in the Internet from local routing in end-user networks (so-called LISP-domains). It also provides additional benefits like simplified multihoming or the avoidance of...

GLI-Split is a new addressing and routing architecture for the Internet. It splits the functionality of current IP addresses into a global locator, a local locator, and an identifier, and encodes them in IPv6 addresses. It implements the locator/identifier split and makes routing in the core of the Internet more scalable. GLI-Split can be increment...

Pre-congestion notification (PCN) in IP networks uses packet metering and marking within a PCN domain to notify its egress nodes whether link-specific admissible or supportable rate thresholds have been exceeded by high priority traffic. Based on this information simple admission control and flow termination is implemented. The latter is a new flow...
